The Zen One swaddle blanket and sleep sack perfectly adapts to your baby's needs - scientifically designed to help babies self-soothe and get sounder sleep Read More
The Zen One swaddle blanket and sleep sack perfectly adapts to your baby's needs - scientifically designed to help babies self-soothe and get sounder sleep as their sleep styles change, from birth through rolling, the Zen One functions as both a snug swaddle and a wearable blanket.
Made of snug but stretchy fabric and loaded with versatile features, the Zen One has 3 gently weighted Cuddle Pads™ that, unlike other baby swaddles, provide comforting pressure only where babies are naturally used to being held, mimicking your embrace and encourage sleep. This light pressure also prevents wakeups from your baby's startle reflex, and helps your baby sleep for deeper, longer stretches.
The Zen One has a snug inner band to hold arms down and prevent startles while your baby sleeps, quick-dry mesh sleeves to help thumb suckers self-soothe, and removable sleeves that allow for arms-out swaddling when your baby rolls and you need to stop swaddling. Whichever way you use the Zen One, a 2-way zipper makes diaper changes a breeze compared to traditional swaddle blankets.
A favorite of over 2 million families, the Zen One is approved by pediatric pulmonologists, exceeds all safety benchmarks. and is backed by a recent university-led weight safety study, so you can sleep soundly knowing your little one is in safe hands in their dream swaddle.

Odalyz M.
Absolutely loved my first one had to order a size up. Only thing was I received one sleeve with a tear. Was super easy to get a replacement, but the replacement was sent in the wrong size. Still waiting on the replacement
Helen H.
My baby loves having one hand zipped up by his face. He sleeps so well with this.
Massiel M.
I have 7-8 lb twins that just turned 2 and the fit is so snug, i ordered a 3-6 month size. I dont know if they need a bigger size or if it should fit like the zipper will burst soon.
Pamela V.
Works wonders! Our baby sleeps great
Kensey L.
Baby can still reach his face which wakes him up and swaddle works great. Took the arms off and working on transition. Needless to say it didn't help him sleep longer which I was hoping it would
Taylor E.
We bought this to try and transition our three month old from the typical “wrapped up/arms confined” swaddle. Little did we know he would end up sleeping through the entire night! This has been the best thing for our baby boy and we cannot recommend it enough! 100/10 would recommend!!!
Emiliya S.
I used it with my son first 6.5 years ago and now with my newborn daughter. I started sleep training her at 2 month in her crib and she was able to self soothe from day 1! The mesh on the hands is genius bc she actually gets to feel her finger and suck on it. Ordering size 3-6 now!
Elisha C.
It's a great transition for my 2-3 month old who was not a fan of the swaddle.
Bridget M.
Not sure if it’s the swaddle or just him getting older/bigger, but my baby is finally napping in his crib for longer than 10 minutes! Regardless of whether it’s helping with sleep, I love how soft and well-designed this is. It’s easy to clean too!
Kenny S.
My son is 6 months old in just a few days. He is very fussy at bedtime. Since I bought the zen 1 sleep sac, he is quiet within 2 minutes and sleeping within 5-10 minutes. He also sleeps through the night. I LOVE the zen 1 sleep sac and recommend it to anyone who has a fussy bedtime baby.
Angela M.
It may not make my baby sleep through the night but he seems content in it. Its soft and durable. Love that the sleeves could be removed.
Taylor B.
We love our Zen one! My 6 week old went from waking up every 2-3 hours during the night to only waking one time, if that, now she sleeps 6-7 hour stretches at night. We both get better sleep and wake up happy! Highly recommend
Tester N.
Been looking for a sleep sack with an internal Velcro wrap. This was a great find. I like the versatility, the weighted area on the front and the quick drying fabric sleeves. My baby has been sleeping well in it, however she’s getting used to being able to suck her fingers through the sleeve, now when I use any other sleep sack, it just gets covered in drool. Would recommend.
Meghan S.
He sleeps so well in this! Going on a week using it and I might need to buy another to size up when he’s bigger.
Ashley B.
Helped me get baby in his bassinet! I was really struggling once we got home from the hospital to get baby boy to sleep/lay flat in his bassinet. Also, he hated being swaddled with his arms down by his side. Thankfully, my sister in law shared her zen one she still had from her little one and it worked the first night! I automatically ordered 3, one for each stage. He likes sleeping with his arms up by his face and eventually we’ll be able to zip off the arms and use for transition. Have only used the 0-3 month one but I’m sure we’ll get good use out of the others as he grows. Love this product.
Jacqui D.
Our little one would only sleep with his hands up. This allows just enough movement but keeps him so calm!
Miranda B.
My baby had better sleep and less wakeups literally in one night! He’s on the bigger side so I was so grateful for the 3-6 month size. This reason alone was enough for me - and that my first son’s sleep sacks were still in beautiful condition even at 3 years old. Love these products.
TAYLOR M.
I love this sleep sack. 10/10 I have to get the bigger one because she grew out of the newborn size.
Basty H.
Our 6 week old son kept waking up every 1-2 hrs at night and now with this sleeper, he sleeps up to 8hrs straight!
Jillian Z.
Band for the chest should be bigger, bought 0-3. (Nb) when my son was 5 weeks old. Was just barely able to touch the Velcro. Aside from that fit well and worked nicely for sleep.
Jacqueline H.
First two nights she slept 9 and 8 hours, when she normally was an up every 2-3 hours baby. Absolutely love this sack!
TyAnna C.
My 4 month old loves having access to her hands, it helps her get back to sleep on her own. I love the get that she has the swaddle feeling without the complete confinement of her hands.
Mackenzie
I am not one to leave a review, but when I tell you this swaddle has been a lifesaving game changer I whole heartedly mean it! We started out swaddling and just slowly stopped, but the startle reflex is so strong for my little one I had to find another option that allowed him to keep his hands beside his head all while holding them down so he doesn’t startle and wake himself all throughout the night. The past two nights my little one has slept 9 hours before waking! I highly recommend!
Lindsey F.
Sleeps so great! So much better than our other sleepers.
Anaiss H.
Amazing. Baby only wakes up one time.
Stephen D.
My son sleeps longer and absolutely loves the sleep sack!
Ashley P.
Our LO moves a lot.. the blanket swaddle was light work for him to bust out of the pre made swaddle was too restrictive… and the wearable blankets don’t swaddle at all so this ended up being perfect for us and he actually gets excited when we put it on him.
Amy B.
Sleeps so soundly in these sacks!
Samantha O.
It’s wonderful! My little guy hates to have both hands swaddled and this is perfect because I can swaddle one arm and he can still soothe with his other! It’s a win win!
Carolyn I.
Such a great swaddle. My baby loves it. Very versatile the options of the arms inside or outside and the ability to unzip the arm section. Such a great quality product
Kelly M.
My daughter in law was so excited!
Krista M.
Love it
Katelyn K.
Kiddo was not sleeping much at all, last night at 3 weeks old he slept through the night! Best investment
Brooke O.
We were in traditional blanket swaddles before trying the zen one sleep sack. Our LO was growing out of the blanket swaddles and was finding his hands more to self soothe. But getting long stretches at night with both his hands out wasn't working since he will flail them around like crazy and wake himself up. We decided to try this sack with one arm out. We started introducing it at nap times and have done a few full nights with it so far. So far he has done so much better than expected with the transition sack! We have had 3 really good nights, last night he did a 9 hour stretch! The only reason I'm detracting a star is because I think they can improve some design elements. Our little guy just turned 3 months and weighs about 15.5 lbs. the middle band that goes around the belly in this sack just barely velcros around him. I'm not sure we will get much longer use out of it and I feel like this could be made to be longer or stretchier. The other element that I think could be improved is the zipper lands really high into the neck, that it ends up poking inward into his neck since it has no where else to go. I think this is a little uncomfortable and maybe they could make it so the neckline scoops down just slightly to avoid this issue. I hope we can get at least one month use out of this sack, but I'm afraid we are going to grow out of it soon!
Cournarier W.
My baby sleeps all night with this on !
Autumn H.
Our favorite swaddle! There’s no breaking free from this one… even if his arms wiggle out of the inner Velcro, I like that they’re caught by the mesh wings. He sleeps soundly all night now because of this swaddle combined with sleep training!
Kim B.
Great product. Perfect fit.
Meghan Z.
My 2 month old son would constantly try to get his arms out of a traditional swaddle. He was barely sleeping. We got this swaddle & he’s been sleeping 6 hours straight and calming himself back to sleep. It’s been a dream!
Saury A.
My baby loves it!
Melissa R.
There’s nothing magical about this swaddle. I did not notice improved sleep. I only gave it 2 stars because I do like the zippers on the arms.
Nohelia A.
Amazing I love how easy it is to help baby transition ! My daughter loves it
Alexis C.
The first one I received ripped at the seam within a few days. The staff went above and beyond and replaced it with a brand new one once I sent the needed photos. Thank you!

Jessie S.
Our baby girl sleeps so well in it!!
Mary C.
Really helped my son sleep! We bought two (as he grew) and are now using it to transition out of a swaddle because the arms zip off. Definitely worth the purchase!
Ashley S.
Easy to put on, keeps baby safe while keeping him cool, and the weighted chest area seems to help!
Stephanie W.
Very pleased and will order again
Stephanie C.
We love this sleep sack because my daughter didn’t need really any time to get used to it, it’s like she felt comfortable in it immediately! She kept getting one arm out of the last swaddle so we left that arm out and kept the other one in. And in no time both arms were out without an issue! Wish I used this for my son when he was a baby.
Emily B.
My baby loves the sleep sack and has been sleeping so well since we got it
Yanet C.
So far, great! According to my daughter’s sleep data, she has more deep sleep moments than with her other sleep sack. She just turned 3 months and the sack is barely the right fit length-wise. I’m worried I spent all that money so that she only wears it for a short period of time. She is also an active sleeper and I tend to leave an arm free but I was confused how to zip the sleep sack while her arm was still flailing around. She eventually figured it out during the night but it took an adjustment from her and me.
corie J.
It was a nice sleep sac but unfortunately, my son hates it
Stefania F.
Shipping was fast and my daughter loves sleeping in it. It’s easy to put on and calms her down right away!
Christen W.
My 2 month old was not sleeping well on his own and he loves to have his hands by his face instead of down in a regular swaddle. It took 2 nights of using this sleep sack, and he has slept 7+ hours overnight ever since!
Stephanie Maree S.
I love the quality but it definitely didn’t work for my son. The ads displayed exactly what he was going through but he actually hated being pinned in.
Robin S.
The material is soft and not heavy. We live in the U.S. Virgin Islands, so finding a sleep sack/swaddle that won't be too hot is really difficult. This one is perfect. We use it with the arms free as he is 4 months old now, and the first night he had it on, he slept 6 hours straight, almost no movement or fussing. We were very surprised and pleased. We were nervous he would have trouble sleeping on his stomach with the weighted chest material, but he is able to roll over onto his stomach and sleep just fine that way. My first order was "lost" while being shipped here; after contacting Nested Bean, they quickly sent me a new one at no charge. Item arrived quickly. Really great customer service and great product. Highly recommend.
Kellie F.
Love this swaddle/sleep sack! The weight is perfect, not too much to be worried about now that she is 3 months old! The mesh sleeves are great as well and I love that they can zip off.
Ryann M.
This swaddle is a game changer for our baby! He sleeps so much better with it and it truly calms him instantly. Can’t recommend enough!
Desirae D.
Perfect for my baby girl. My boy loved sleeping with his, so I knew I had to buy one for my little girl.
Melody M.
Our baby is still a tricky sleeper but can now self soothe with the swaddle!!
Caryn G.
Baby’s sleep isn’t much different than it was but he wasn’t bad to begin with. Adorable and soft but took about two or more weeks to arrive.
michaela s.
This product really works for my baby who keeps escaping the swaddle. Great transition from swaddle to this . I’m impressed!
Jax L.
Baby absolutely loves it!
Jenna L.
My baby hates this…. I am sad about it
Because it was expensive
Alexandra M.
My baby is 3 months old and she still like to feel she is been hold, and the swaddle help her to fall sleep almost immediately
Kaitlyn F.
Slept 9 hours the first time wearing it
Ryann M.
My 2 month old was sleeping for about a 5-6 hour stretch at night and couldn’t settle after that. I was skeptical about this swaddle for awhile but I finally risked it and got it and it is a GAME CHANGER. He now sleeps for 10-12 hours a night uninterrupted. Its amazing! The slight weight calms him almost instantly when we put him in it and he loves still having access to his hands without his arms fully out, I highly recommend this swaddle/sleep sack! It’s amazing.
Meghann M.
Really cool product for my active-armed little girl. She seems very comfortable in it and getting it on is a breeze which you know is key for any baby product. Love it! Bought the next size up for the next transition!
Stacey M.
We love our Zen sleeper! It has helped so much with night time sleeping!
Eric J.
Our little man sleeps so much better with his new swaddle! We love it and strongly reccomend.
Erin P.
Finally we are sleeping for 3 to 4 hour stretches. We have been up every 1 to 2 hours until we started using the zen swaddle. Highly recommend.
Emily M.
Newborn loves it!
Salam H.
Ordered 2 for our 4 month old twins. One has a hole in it to start but both twins were not fans. The minute we start putting it on, they cry. For the first week, they were waking up twice as much during the night. Then they went back to the same routine. They did not sleep any better with it then without it. I do like however that it is warm. That’s about it. Totally overpriced in my opinion.
Pessy K.
This is amazing!
Emily B.
Unfortunately this didn’t work for our daughter. She seemed to sleep worse with it on. I had high hopes but our swaddle search continues!
Krystal A.
…
Thalia C.
My baby refused to sleep in her bassinet despite trying other swaddles and sleep sacks. We finally got this one and she finally sleeps in her own bassinet with arms up because she hates being swaddled. For reference she is 4 weeks old. We love this product.
samantha B.
I did not find this item to help my child sleep any better than any other swaddle. If anything, I think she became more fussy in her sleep while wearing it. I don’t even use it anymore.
Adele C.
Good quality, my baby fell asleep right away!
Erin A.
Getting a full night of sleep with twins!
Caelan W.
Little guy went from up every two hours to 4 to 5 hour spurts! It’s well worth it!
Julia V.
My little one loves his nested bean! The transition from swaddle to this was much easier than I anticipated. Thank you nested bean!
Alysia F.
My son LOVES his Neated Bean Zen One Classic! The fabric is super soft and breathable and I love that you can unzip the arms. The little weighted area is the perfect weight! I will definitely be purchasing more!!
Salam H.
I thought “weighted” meant the entire thing is weighted but no. There’s a little pound in the front and that just has a little weight in it. My babies hated this and won’t up more often during the night. That’s a parents worst nightmare
Ani N.
My baby did not like it it made him really sweaty and uncomfortable
Kenzie D.
My LO is less than 2 months and sleeping 7-9 hour stretches during the night in the nested bean transitional sleep sac. The only negative I have to say is my baby is long and the 0-3 month is already too small. Don’t worry, I’ve bought 3 more 3-6 month and will continue to purchase more! A huge believer in these things!
Kelly M.
This is perfect for my 3 month old who loves to suck on her hands to self soothe !!! The other sleep sacks we use she sucks on them and it makes the fabric soaking wet and stinky! I was constantly having to wash it after each sleep !!! The mesh is perfect!
Katherine R.
Super soft material—comfortable for our newborn. Our son definitely likes the zen one sleep sack better than a swaddle. He was constantly breaking out of the swaddle or grunting & fighting it throughout the night. The weighted bean has also helped when putting him in the bassinet & no longer having to keep my hand on his chest. He is definitely sleeping better since we switched. Only reason for four stars is the length of sack if you’re baby is tall they will likely outgrow this quickly. Our son is two months I bought the 3-6 month size as he is big for his age but he is already filling out the entire sleep sack.
Michelle H.
Love it , baby loves it ! Works wonders .
Megan H.
Has completely improved babe's sleep
Megan H.
Babe has been sleeping so much better since using this sleep sack!
Amelia B.
I call this my secret weapon, I truly believe this is the only reason my baby is sleeping better at night!
Caroline B.
My little girl absolutely loves sleeping in these! Made the transition from the traditional swaddle to this so much easier!
Kendall G.
One of the best purchases I’ve ever made!
Courtney N.
Took a while to get here. My baby doesn’t like his arms in the upper part of the sleep sack. I wish they made this one so you could swaddle the baby with arms at his side.
Allison T.
I’m going to be honest, it’s an amazing product and it actually works. But the price point is super high. There are desperate newborn parents that crave sleep so bad they’re willing to pay the increased price for a good nights sleep for themselves and their baby, but that doesn’t mean a swaddle needs to be near $60. It almost seems unfair. Please consider lowering the price in some direction as it will allow more parents to recommend this product to other parents rather than a cheaper alternative.
Monica G.
Just one week of use and baby is putting himself to sleep for every nap and night time!
Alia A.
didnt work for my baby but, good idea.
Pamela M.
My daughter loves these, she used them for her first baby, so I bought her more for her second child due in December.
Madison C.
Only thing she will sleep in! We’ve tried other swaddles but she just wiggles out. We put her in this and she’s out like a light! It’s also helped with getting her to sleep in her bassinet because when setting her down, she doesn’t startle and wake herself up. 10/10 would recommend!!!
Kacy S.
Perfect for transitioning out of a traditional swaddle!

She kept getting one arm out of the last swaddle so we left that arm out and kept the other one in. And in no time both arms were out without an issue! Wish I used this for my son when he was a baby.

My baby loves the sleep sack and has been sleeping so well since we got it

So far, great! According to my daughter’s sleep data, she has more deep sleep moments than with her other sleep sack. She just turned 3 months and the sack is barely the right fit length-wise. I’m worried I spent all that money so that she only wears it for a short period of time. She is also an active sleeper and I tend to leave an arm free but I was confused how to zip the sleep sack while her arm was still flailing around. She eventually figured it out during the night but it took an adjustment from her and me.

It was a nice sleep sac but unfortunately, my son hates it
Stefania F.
Shipping was fast and my daughter loves sleeping in it. It’s easy to put on and calms her down right away!

My 2 month old was not sleeping well on his own and he loves to have his hands by his face instead of down in a regular swaddle. It took 2 nights of using this sleep sack, and he has slept 7+ hours overnight ever since!
Stephanie Maree S.
I love the quality but it definitely didn’t work for my son. The ads displayed exactly what he was going through but he actually hated being pinned in.

The material is soft and not heavy. We live in the U.S. Virgin Islands, so finding a sleep sack/swaddle that won't be too hot is really difficult. This one is perfect. We use it with the arms free as he is 4 months old now, and the first night he had it on, he slept 6 hours straight, almost no movement or fussing. We were very surprised and pleased. We were nervous he would have trouble sleeping on his stomach with the weighted chest material, but he is able to roll over onto his stomach and sleep just fine that way. My first order was "lost" while being shipped here; after contacting Nested Bean, they quickly sent me a new one at no charge. Item arrived quickly. Really great customer service and great product. Highly recommend.

Love this swaddle/sleep sack! The weight is perfect, not too much to be worried about now that she is 3 months old! The mesh sleeves are great as well and I love that they can zip off.
Ryann M.
This swaddle is a game changer for our baby! He sleeps so much better with it and it truly calms him instantly. Can’t recommend enough!
Desirae D.
Perfect for my baby girl. My boy loved sleeping with his, so I knew I had to buy one for my little girl.
Melody M.
Our baby is still a tricky sleeper but can now self soothe with the swaddle!!
Caryn G.
Baby’s sleep isn’t much different than it was but he wasn’t bad to begin with. Adorable and soft but took about two or more weeks to arrive.
michaela s.
This product really works for my baby who keeps escaping the swaddle. Great transition from swaddle to this . I’m impressed!
Jax L.
Baby absolutely loves it!
Jenna L.
My baby hates this…. I am sad about it
Because it was expensive
Alexandra M.
My baby is 3 months old and she still like to feel she is been hold, and the swaddle help her to fall sleep almost immediately
Kaitlyn F.
Slept 9 hours the first time wearing it
Ryann M.
My 2 month old was sleeping for about a 5-6 hour stretch at night and couldn’t settle after that. I was skeptical about this swaddle for awhile but I finally risked it and got it and it is a GAME CHANGER. He now sleeps for 10-12 hours a night uninterrupted. Its amazing! The slight weight calms him almost instantly when we put him in it and he loves still having access to his hands without his arms fully out, I highly recommend this swaddle/sleep sack! It’s amazing.
Meghann M.
Really cool product for my active-armed little girl. She seems very comfortable in it and getting it on is a breeze which you know is key for any baby product. Love it! Bought the next size up for the next transition!
Stacey M.
We love our Zen sleeper! It has helped so much with night time sleeping!
Eric J.
Our little man sleeps so much better with his new swaddle! We love it and strongly reccomend.
Erin P.
Finally we are sleeping for 3 to 4 hour stretches. We have been up every 1 to 2 hours until we started using the zen swaddle. Highly recommend.
Emily M.
Newborn loves it!
Salam H.
Ordered 2 for our 4 month old twins. One has a hole in it to start but both twins were not fans. The minute we start putting it on, they cry. For the first week, they were waking up twice as much during the night. Then they went back to the same routine. They did not sleep any better with it then without it. I do like however that it is warm. That’s about it. Totally overpriced in my opinion.
Pessy K.
This is amazing!
Emily B.
Unfortunately this didn’t work for our daughter. She seemed to sleep worse with it on. I had high hopes but our swaddle search continues!

My baby refused to sleep in her bassinet despite trying other swaddles and sleep sacks. We finally got this one and she finally sleeps in her own bassinet with arms up because she hates being swaddled. For reference she is 4 weeks old. We love this product.
samantha B.
I did not find this item to help my child sleep any better than any other swaddle. If anything, I think she became more fussy in her sleep while wearing it. I don’t even use it anymore.
Adele C.
Good quality, my baby fell asleep right away!
Erin A.
Getting a full night of sleep with twins!
Caelan W.
Little guy went from up every two hours to 4 to 5 hour spurts! It’s well worth it!
Julia V.
My little one loves his nested bean! The transition from swaddle to this was much easier than I anticipated. Thank you nested bean!
Alysia F.
My son LOVES his Neated Bean Zen One Classic! The fabric is super soft and breathable and I love that you can unzip the arms. The little weighted area is the perfect weight! I will definitely be purchasing more!!
Salam H.
I thought “weighted” meant the entire thing is weighted but no. There’s a little pound in the front and that just has a little weight in it. My babies hated this and won’t up more often during the night. That’s a parents worst nightmare
Ani N.
My baby did not like it it made him really sweaty and uncomfortable
Kenzie D.
My LO is less than 2 months and sleeping 7-9 hour stretches during the night in the nested bean transitional sleep sac. The only negative I have to say is my baby is long and the 0-3 month is already too small. Don’t worry, I’ve bought 3 more 3-6 month and will continue to purchase more! A huge believer in these things!
Kelly M.
This is perfect for my 3 month old who loves to suck on her hands to self soothe !!! The other sleep sacks we use she sucks on them and it makes the fabric soaking wet and stinky! I was constantly having to wash it after each sleep !!! The mesh is perfect!
Katherine R.
Super soft material—comfortable for our newborn. Our son definitely likes the zen one sleep sack better than a swaddle. He was constantly breaking out of the swaddle or grunting & fighting it throughout the night. The weighted bean has also helped when putting him in the bassinet & no longer having to keep my hand on his chest. He is definitely sleeping better since we switched. Only reason for four stars is the length of sack if you’re baby is tall they will likely outgrow this quickly. Our son is two months I bought the 3-6 month size as he is big for his age but he is already filling out the entire sleep sack.
Michelle H.
Love it , baby loves it ! Works wonders .
Megan H.
Has completely improved babe's sleep
Megan H.
Babe has been sleeping so much better since using this sleep sack!
Amelia B.
I call this my secret weapon, I truly believe this is the only reason my baby is sleeping better at night!
Caroline B.
My little girl absolutely loves sleeping in these! Made the transition from the traditional swaddle to this so much easier!
Kendall G.
One of the best purchases I’ve ever made!
Courtney N.
Took a while to get here. My baby doesn’t like his arms in the upper part of the sleep sack. I wish they made this one so you could swaddle the baby with arms at his side.
Allison T.
I’m going to be honest, it’s an amazing product and it actually works. But the price point is super high. There are desperate newborn parents that crave sleep so bad they’re willing to pay the increased price for a good nights sleep for themselves and their baby, but that doesn’t mean a swaddle needs to be near $60. It almost seems unfair. Please consider lowering the price in some direction as it will allow more parents to recommend this product to other parents rather than a cheaper alternative.
Monica G.
Just one week of use and baby is putting himself to sleep for every nap and night time!
Alia A.
didnt work for my baby but, good idea.
Pamela M.
My daughter loves these, she used them for her first baby, so I bought her more for her second child due in December.
Madison C.
Only thing she will sleep in! We’ve tried other swaddles but she just wiggles out. We put her in this and she’s out like a light! It’s also helped with getting her to sleep in her bassinet because when setting her down, she doesn’t startle and wake herself up. 10/10 would recommend!!!

Perfect for transitioning out of a traditional swaddle!
Frequently asked questions
-
How can the Nested Bean Zen One™ be used in different ways?
The Zen One adapts to your baby’s unique sleep style at every stage, from birth through rolling—the perfect 3 to 6-month swaddle. As a newborn swaddle, a secure inner band holds arms down to prevent the startle reflex. For little finger suckers, the Nested Bean Zen One™ has breathable mesh sleeves that keep hands in but accessible, so babies can self-soothe. As baby shows signs that they're starting to roll, removable sleeves allow for swaddling your baby arms-out. At every stage, built-in Cuddle Pads™ provide gentle pressure that mimics the feel of your embrace, so your swaddled baby still experiences uninterrupted comfort and improved sleep.
-
How much weight is in the Nested Bean Zen One™ transitional swaddle?
The Nested Bean Zen One™ swaddle includes 3 gently weighted sections, two on the sides and a self-contained Cuddle Pad™ in the center. The weighted areas of the product are 30 gramsvfor the NB size and 40 grams for the Small size. Use the Nested Bean Zen One™ from birth, or as the perfect 3 to 6-month swaddle to accommodate changing sleep preferences. It is safely calibrated only in the center to feel as gentle as your palm on their chest, instead all weighted blankets, which the AAP has deemed unsafe for infants.
-
When should I transition my baby out of the Nested Bean Zen One™ swaddle?
With most swaddles, once your baby starts begins to roll over, it's time to begin the transition from a swaddle to a sleep sack. But the Nested Bean The Zen One™ can safely be used as a 3 to 6-month swaddle—even if your baby has started to roll—by removing the mesh sleeves and swaddling arms-out.
-
What is The Cuddle Effect™—and how can the Nested Bean Zen One™ trigger it?
The Cuddle Effect is a proven metabolic response that babies experience when they are held, that triggers relaxation and well-being, improves sleep and promotes healthy development. Research on Deep Touch Pressure (DTP) shows that babies experience the Cuddle Effect when they feel gentle pressure in the places you naturally hold them. The Nested Bean Zen One ™ is designed with gently weighted Cuddle Pads™ that calm like your embrace to reduce wakeups from the startle reflex and promote the Cuddle Effect. The perfect 3 to 6-month swaddle for changing sleep preferences.
-
Can I use the Nested Bean Zen™ One with my baby’s arms free? Is it convertible?
Yes - unlike a traditional transitional swaddle blanket, the Zen One is designed with arms-free swaddling in mind. To use the Zen One™ with arms out, remove the mesh sleeves from the swaddle.
-
How do I know which mesh sleeve goes on which side of the Nested Bean™ Zen One?
When reattaching the sleeves on the Nested Bean Zen One™, the zipper should start at the back of the product and zip over the baby’s shoulder to the front. The final position should be at your baby’s armpit. If you’re having trouble zipping the sleeves back on, try switching them.
-
Does the Nested Bean Zen One™ meet industry safety standards?
The Nested Bean Zen One™ transitional swaddle adheres to all known mandatory standards for children's apparel for product construction, flammability and more. The Cuddle Pad™ in the Nested Bean Zen One™ is self-contained and cannot cause overheating, and the gentle weight provides uninterrupted comfort.
-
How has the Zen One design improved?
Babies may have different preferred positions of holding their arms as they sleep. After listening to thounsads of customer comments, we have modified the Zen One sleeves to accomodate every baby's preference. The sleeve design allows for a wider range of arm movements, while the stretch fabric and mesh sleeves offer the necessary restraint from startles.
-
How do Nested Bean Zen One™ swaddles hold up in the washing machine?
Nested Bean Zen One™ transitional swaddles are made of the highest-grade fabrics, and, as essential 3 to 6-month swaddles, are designed to withstand multiple washings. To protect the fabric quality, we recommend washing them in cold water, on a gentle cycle and tumble dry on low heat.
-
Does the Nested Bean Zen One™ allow for easy diaper changes?
Yes. The 2-way zipper on the Nested Bean Zen One™ makes nighttime changes a breeze—no disruptive ‘un-swaddling’—so babies can sleep through diaper changes.
